John: I started seeing the same problem for the first time a few weeks ago,
and I performed the fix you described back in July on connector J8. That
solved the problem for me, but it's always a possibility that simply
disassembling the case is actually repairing another lose wire or circuit
board trace somewhere else.
The interesting clue is that the RIT/XIT control is the one that seems to
have the most problems even though it's generally used less than the Multi
or Main AF encoders by most ops. I'm still suspicious of the cable. Those
ribbon connectors with the "wire stabs" that punch through the insulation
have failed on me in other types of equipment. Perhaps swapping the two
cables might cure the problem, or make it manifest itself in a different
way.

Subject: [TenTec] RIT/XIT Problem back
After all my work, the intermittent RIT/XIT problem is back! :={ This time
I
am going to use the standoffs that Ten-Tec sent me so I can mount the
front
panel away from the case. Then when the control does not work, I can use a
plastic stick and touch suspect parts and see if it starts working again.
It
is not going to be easy because I can make it work again just by pressing
on
the front panel. That is why some people had said pulling knobs cured the
problem. More to come. And I thought for sure I had it when I found the
pins
with no evidence of rubbing the socket.
73,
John
